She's proud and patriotic! Minka Kelly is so supportive of her boyfriend Chris Evans that she has a Captain America iPhone cover. The Butler actress, 33, showed off her latest tech accessory during a movie date with Evans, 32, at ArcLight Cinemas in L.A. on Friday, July 5. The couple dressed casually for the outing, wearing jeans, sneakers and T-shirts.

"The two of them really compliment each other," a source tells UsWeekly of the actors, who briefly dated in 2007 before reconnecting last summer. "Chris is much more of a homebody now and doesn't really go out. Same goes for Minka. Things are going really well with them."

Though Evans bought a house in the Hollywood Hills for $3.52 million in May, another insider says Kelly is not moving in. Even so, his on-again love "is helping a lot with all the decorating details." The insider adds that stars are "still really serious" about each other.
